Abstract
We report improved performance from ITO- free organic light emitting diodes (OLEDs) prepared with vapour phase polymerization poly(3,4-ethylenedioxythiophene) (VPP-PEDOT) anodes. By inserting additional interfacial anode layers based on triarylamine polymers, we demonstrate VPP-PEDOT OLEDs on rigid glass substrates that display improved electroluminescence characteristics, and which have efficiencies that are comparable to equivalent ITO-based devices. We also report on the development of flexible OLEDs (FOLEDs) with VPP-PEDOT anodes, demonstrating efficient red, green, blue and white-emitting devices with significantly improved device rectification.
